American Stroke Association says Weather changes may be linked to Stroke Hospitalizations, Death Rates

 

American Stroke Association - American Heart AssociationSan Diego, CA – Stroke hospitalization and death rates may rise and fall with outdoor temperature and dew points, according to research presented at the American Stroke Association’s International Stroke Conference 2014.

Researchers studied a sample of 134,510 people who were 18 or older when admitted to hospitals in 2009-10 for ischemic stroke — a stroke caused by a blood clot that blocks blood flow in or near the brain. They then obtained temperature and dew point data during that period. «Read the rest of this article»

American Stroke Association says Vaccines may lower Kids’ Stroke Risk

 

American Stroke Association - American Heart AssociationSan Diego, CA – Routine vaccinations may reduce the higher risk of stroke in children that is associated with common infections, according to research presented at the American Stroke Association’s International Stroke Conference 2014 in San Diego.

In a large, international study, researchers are examining the link between infections and ischemic stroke – those caused by a clot blocking blood flow in or near the brain. «Read the rest of this article»

American Stroke Association reports Sleep Apnea more common in people with Stroke-related Brainstem Injuries

 

American Stroke Association - American Heart AssociationSan Diego, CA – People whose strokes affected their brainstems had a significantly higher prevalence of sleep apnea than those whose stroke affected other parts of the brain, according to research presented at the American Stroke Association’s International Stroke Conference 2014.

Sleep apnea is marked by interrupted breathing during sleep and can lead to serious health problems including heart disease and stroke. «Read the rest of this article»

American Stroke Association reports awareness, response key for Stroke in Children

 

American Stroke Association - American Heart AssociationSan Diego, CA – Parents and healthcare professionals must be aware that children can have strokes and be prepared to respond to symptoms, according to research presented at the American Stroke Association’s International Stroke Conference 2014.

As in adults, warning signs of stroke in children are: sudden weakness or numbness of the face, arm or leg; sudden difficulty in speaking; sudden problems in seeing; sudden difficulty walking; dizziness; or sudden onset of headache.

NASA’s Mars Reconnaissance Orbiter snaps image of new impact Crater on Mars

 

Written by Guy Webster
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today.

The image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter shows a crater about 100 feet (30 meters) in diameter at the center of a radial burst painting the surface with a pattern of bright and dark tones.

A dramatic, fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Nov. 19, 2013.

NASA’s Mars rover Curiosity catches images of Mars’ moon Phobos eclipsing the Sun

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – Images taken with a telephoto-lens camera on NASA’s Mars rover Curiosity catch the larger of Mars’ two moons, Phobos, passing directly in front of the sun — the sharpest images of a solar eclipse ever taken at Mars.

Phobos does not fully cover the sun, as seen from the surface of Mars, so the solar eclipse is what’s called a ring, or annular, type. A set of three frames from Curiosity’s Mast Camera (Mastcam), taken three seconds apart as Phobos eclipsed the sun here .

This set of three images shows views three seconds apart as the larger of Mars' two moons, Phobos, passed directly in front of the sun as seen by NASA's Mars rover Curiosity. Curiosity photographed this annular, or ring, eclipse with the telephoto-lens camera of the rover's Mast Camera pair (right Mastcam) on Aug. 17, 2013, the 369th Martian day, or sol, of Curiosity's work on Mars.

NASA’s Curiosity Rover catches images of Mars’ Moons Phobos, Deimos

 

NASA - National Aeronautics and Space AdministrationPasadena, CA – The larger of the two moons of Mars, Phobos, passes directly in front of the other, Deimos, in a new series of sky-watching images from NASA’s Mars rover Curiosity.

Large craters on Phobos are clearly visible in these images from the surface of Mars. No previous images from missions on the surface caught one moon eclipsing the other.

NASA reports Project 1640 explores the Atmosphere of Planets far away

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – Gone are the days of being able to count the number of known planets on your fingers. Today, there are more than 800 confirmed exoplanets — planets that orbit stars beyond our sun — and more than 2,700 other candidates.

What are these exotic planets made of? Unfortunately, you cannot stack them in a jar like marbles and take a closer look. Instead, researchers are coming up with advanced techniques for probing the planets’ makeup.

This image shows the HR 8799 planets with starlight optically suppressed and data processing conducted to remove residual starlight. The star is at the center of the blackened circle in the image. The four spots indicated with the letters b through e are the planets. This is a composite image using 30 wavelengths of light and was obtained over a period of 1.25 hours on June 14th and 15th, 2012. (Image courtesy of Project 1640)

NASA’s Kepler space telescope discovers White Dwarf bending light of nearby Star

 

Written by Whitney Clavin
NASA’s Jet Propulsion Laboratory

NASA - National Aeronautics and Space AdministrationPasadena, CA – NASA’s Kepler space telescope has witnessed the effects of a dead star bending the light of its companion star. The findings are among the first detections of this phenomenon — a result of Einstein’s general theory of relativity — in binary, or double, star systems.

The dead star, called a white dwarf, is the burnt-out core of what used to be a star like our sun. It is locked in an orbiting dance with its partner, a small “red dwarf” star. While the tiny white dwarf is physically smaller than the red dwarf, it is more massive.

This artist's concept depicts a dense, dead star called a white dwarf crossing in front of a small, red star. The white dwarf's gravity is so great it bends and magnifies light from the red star. (Image credit: NASA/JPL-Caltech)
